If you used Adobe Gamma to calibarate your monitor, then the monitor profile it created will still be in your system folder and will be loaded at startup. The rest of it it basically a 1 for 1 copy and paste of you Actions, Gradients, Plugins, Presets, etc. At least that is the safe way to do it. I would not recommend copying the prefs file from a former version as it is likely to cause PS to crash. Beside it should only take you a few minutes to set your preferences and color settings again.
